Re: Boiler Piping question
Your letter looks fine. I believe you should send it by certified mail with a return receipt. You will probably get a phone call the day the letter is delivered.
Hopefully this will get you in a better place with a lower oil bill.

The Significance Of The Fire
The Significance Of The Fire
The Irish made fires that never went out. The fire in the hearth was for cooking and for warmth, and it smoldered for hundreds of years in some cases. In this episode, Dan Holohan reflects on his heating heritage.
Re: 2 zones, 2 pumps. 2 flow control valves?
There are two reasons for Flow Control Valves
1. On a tankless coil for DHW boiler you do not want gravity flow from the boiler that is maintaining a minimum temperature. the Flow Control/ FloChek. or IFC check valve in the pump (if it is on the supply) will keep that from happening;
2. To keep a zone circulator from drawing water backwards thru the piping of a zone that is not operational.
Look in this book called Pumping Away starting on page 9. The illustrations and text are really easy to follow.

Why not just take one out and try the ones you have? That will tell you if you have the correct thread.
Re: Viessmann Vitodens 100 WB1B-35 Burner Screws
If it's the screws that attach the burner to the burner door here are some photos. they do come with a new burner tube assembly if you decide you need to make sure they are correct. Its kind of strange to need all 4 of these and not have one for reference though? mind sharing what happened?

Re: Viessmann Vitodens 100 WB1B-35 Burner Screws
Are these the screws that are inside the unit, that attach the burner tube to the burner plate? or the screws that hold the burner door/plate to the heat exchanger?

Re: Help Identifying Manufacturer of Non-Electric Zone Valve
I just got hold of some replacements for "Ammark" TRV's.
They also are made in Austria.

Re: Help Identifying Manufacturer of Non-Electric Zone Valve
Looks like a TRV actuator from another manufacturer would probably fit on that valve.
